QQ for you - i am installing my RaceChip Ultimate Pro and the instructions are ****.
I found the Common Rail connection - total pain in the *** to get to.
Having a harder time identifying the "turbo boost pressure sensor" The pic if looking at the engine is front left - in front of Common Rail - i know it is hard to view.
worst case i take to my shop and he hook it up in 10 mins.
How's the performance? I tried it on my ML Bluetec for a few months.
love the new tq curve - uphill pulls even more of a bast and off the line you can feel the increased tq. Had my mechanic install for me and he did a side by side comparison and he said he felt a significant difference.
Freeway passing definitely feels like it should - way less lag -
I purchased the Ultimate Race Chip and would highly recommend.

I bought one for my GL63 and returned it because one of the sensor points was a nightmare to connect, instructions were rubbish like you say and when asking RaceChip they simply replied saying they couldn’t help, WTF!!
Not great service so dread to think how they treat customers when theres a problem
It gave some pretty nice gains for my GL63 for a very reasonable price but the DIY bit and poor customer support stopped me from installing.
The sensor identified as B on the attached is burried and difficult to access, some online videos suggested the needed for a dental pick but in the end I gave up and returned mine. Probably easy to those that have worked on engines before so if anyone knows a trick to get it released let me know and I can but it again
